  • Bobcat 225 NT runs for a few minutes, then dies.

    When my 225NT is cold, it cranks and runs great for 5 minutes and then suddenly dies.
    I've tested and it's cutting power to the coil for some reason.
    I've replaced the coil, condenser and crossed the low oil sensor.
    Anyone have any ideas?

    Did it perhaps run to low oil shutdown at one time recently?
    Are you running the correct oil in the engine?

    Have you removed the spark plugs and determined how easily the machine rolls over by hand when hot?

    How did you determine it's cutting power to the coil?

      As for your first question, I don't know. (I just bought it)

      I have not tried rolling it by hand when hot. I'll try that, but I'm pretty sure it's not going to be an issue.

      I put a test light on the wire coming to the coil and it is the first thing to shut off (immediately followed by the motor shutting down).

        Is this a Kohler or Onan engine?

            Is the test light from block ground to coil + or across the coil?

            Honestly you may find your problem better answered on Smokstak.com where there is a hip deep yard full of Onan guys.

              Thank you. I'll try that. I'll keep watching this thread as well, in case someone here can help.
